Fluke 743B

Documenting Process Calibrator

The Fluke 740 Series is a handheld documenting process calibrator for industrial instrumentation. It measures and sources voltage current resistance frequency temperature pressure signals. It captures calibration results for traceable documentation and data storage. Selected models provide HART communication for smart transmitter calibration.
